2 Claims. The present invention relates generally to envelopes, and more particularly'to envelopes designed for attachment to packing cases and the like, for receiving and enclosing lists, invoices, and other data and material relating to the contents of the case or box.

Such an envelope, after receiving its lists, invoices, or other enclosures, is ordinarily secured to the packing box or case by tacks or nails driven through its four corners. -I-Ieretofore, in order to avoid mutilation of the envelopes contents by such tacking or nailing, it has been the practice, in the manufacture of such an envelope, to provide a metal eyelet at or near each corner, to receive the nail, tack or other fastening device; the provision of such eyelets, or equivalent protective devices, involves extra manufacturing operations that greatly increase the cost of these packing or invoice envelopes.

My invention provides a solution of this difficulty by an envelope construction which, in the absence of eyelets, or equivalent protective devices, is susceptible of being secured by nails or tacks to the box or case, Without risk of mutilating the envelopes contents. Other and further objects and advantages of my invention will be made apparent in the following detailed description thereof, taken in connection with the accompanying drawing, in which- Fig. 1 is an extended plan view of the blank from which the envelope of my invention is constructed. I I

Fig. 2 shows the initial folding operation performed on said blank, in the manufacture of my improved envelope.

Fig. 3 is a rear view of said envelope, as completed by a second folding operation.

Fig. 4 is a large scale sectional View, the section being taken on the line 44 of Fig. 3, and

Fig. 5 is a perspective view illustrating the envelope as secured by tacking or nailing to a packing case or box.

Like reference characters refer to like parts in the different figures.

The envelope of my invention is preferably made from strong durable paper stock, such as manila, kraft, or the like, which is cut to provide blanks of substantially the shape and configuration shown by Fig. 1. Each such blank, as shown in Fig. 1, comprises a generally rectangular body portion I, as outlined laterally by the broken lines 2, 3, and at its ends by the broken lines 4, 5. Said body portion I provides the envelopes front wall; three integral flap extensionsjrom said body portion provide, when folded over and boundary 4 of body glued together, the envelopes rear wall. One of these is a'back flap 6 extending from the lower portion I, said flap 6 being of substantially the same height as said body portion I, but appreciably narrower in width. The other two are side flaps I and 8 which flank the body portion I along its lateral boundaries 2 and 3, theses'ide flaps being of sufficient width to overlap with the side edges of back flap 6 afterthe latter (see Fig. 2) has-been folded on line 4 to overlie the body portion I The blank of Fig. 1 also includes, as an integral extension of body portion I, a fourth flap 9 extending from theupper boundaryv 5 of said body portion. I, and adaptedto serve in the well known manner as a closure for the upper open end or mouth of the envelope.

In the manufacture of my improved envelope from the blank of Fig. '1, the initial folding operation for the formation of the envelope pocket involves (see Fig. 2) the disposal of flap 6 in face-to-face relation to the body portion I, by a transverse fold on the line 4, which latter coincides in the completed envelope with the bottom of the pocket. It will be noted that the above-described folding over of flap 6 onto body portion I leaves uncovered and exposed along the side of said body portion I the marginal areas III, II of appreciable width, for a purpose to be presently described.

The next folding operation which completes the envelope. pocket involves (see Fig. 3) the folding over of the side flaps 1 and 8 on the respective lines 2 and 3; previous to such folding, glue or other suitable adhesive is applied, either to' the flaps I and 8 themselves, as shown in Fig. 1, or to the areas which they cover when folded over, as shown in Fig. 2, Via, the aforesaid marginal areas III and II of the body portion and the immediately adjacent side margins I2 and I3 of the outside face of folded-over flap 6. In other words, this gluing, in either case, involves two stripes or bands of adhesive, each of a Width that appreciably exceeds the width of the adhesive seams formed by the overlap of flaps 1 and 8 upon the margins I2 and I3 respectively of back flap 6, the excess width of such glue producing, as shown in Figs. 3 and 4, the firm 'adhesion of the flaps l and 8 to the aforesaid side marginal areas I0 and I I of the body portion I, so that the envelope pocket, instead of being as wide as the distance between the fold lines 2 and 3, is only as wide as the'back flap 6, said pocket, in the completed envelope, being *flanked along each side edge by stuck-together doubleflap 9 against thickness strips of envelope material lying beyond the seams formed by the flaps 1 and 8 with the back flap 6.

Thus, an enclosure such as indicated at l4, Fig. 3, when inserted in the envelope, is prevented by such double-thickness stuck-together strips from reaching or extending to the envelopes side edges formed by the fold lines 2 and 3; in other words, the curtailment so efiected in the width of the pocket or enclosure-receiving space renders the envelope susceptible of being nailed 1 or tacked to a packing box or case l8 without danger of, mutilating the enclosure M, the nails or tacks l5, 15 being driven (see Fig. 5) through the double-thickness material along the side edges of the envelope and outside'of the pockets area. Hence, it is unnecessary to provide my envelope for the purposes of such tacking -or nailing, with the usual metal eyelets or equiv; alent protective devices which has heretofore been employed in envelopes of this class to save the contents of the'envelopes from mutilation or tearing.

adapted for attachment by tacks or nails to a box, case or the like, said envelope being made from .a one-piece blank having a substantially rectangular body portion forming one envelope wall, and having a back flap and two side flaps, the latter being folded over and adhesively united in overlapping relation to the side edges of said for the formation of the other envelope wall, said side edges of saidback flap being appreciably spaced from the lines of fold of said side flaps, and the latter between said lines of fold and said side edges being adhesively'united to said body portion, thereby to form, beyond the side edges of the envelope pocket or contents-receiving space, areas of appreciable width for the driving of said tacks or nails without damage to the contents of said pocket.

2. As a new article of manufacture, an envelope adapted for attachment by tacks or nails to abox, case or the like, said envelope being made from a one-piece'blank having a substantially rectangular body portion forming one envelope wall, and having a back flap and two side flaps, the latter being folded over and adhesively united in over-lapping relation to the side edges of said back flap, for the formation of the other envelope wall, the latter thereby having two side seams, said seams being appreciably spaced from the lines of fold of said side flaps, and the intervening side flap material being adhesively united to the underlying areas of said body portion, whereby to formareas for the driving of said tacks or nails without damage to the contents of the envelope pocket between said walls.
